Bronco instrument cluster
I've recently purchased a 66-77 bronco cluster for my 66 f250. It originally had the sweep speedo which was broken, then replaced with the round speedo, What exactly will I need to do to hook up the alt and oil gauge?
They are set up as dummy lights on my truck and for the life of me i cannot find the thread where another member swapped his over. Any pics and tips would be appreciated, Thanks guys.

The Amp Gauge is simpler take the main wire from the Solenoid to the fuse box, and run it through the little wire that clamps at the back of the amp gauge, it picks up the ambient electrons and measures them. Works like a champ.

The accessory alt and oil pressure gauges seen on alot of the trucks with the sweep speedo as well as some with the round speedo utilized a seperate harness entirely to get them to work. its a plug and go setup...
If your truck originally had the 2 gauges, all you should have to do is mount the gauges...I havent seen an early Bronco bezel/cluster in years so Im assuming its essentially the same as the pickups with the 2 round areas opposite of the speedo on both sides. The round speedo area itself was never intended to have the alternator or oil pressure gauges...just fuel and temp...

This may be of some help wiring the Bronco gauges. Fuel, temp and oil pressure work off the instrument voltage regulator. Ammeter is already answered. Actually I did away with the ammeter when converting to 3G alternator and replaced it with a voltmeter.

Awesome thanks, @camperspecial my truck did have those two gauges as well however they didn't work so I replaced them with a mechanical oil gauge and voltmeter. With this setup I could replace the oil gauge with a small tachometer.
Thanks for the info guys! if you have anymore let me know.
